Description

technical field [0001] The invention belongs to the field of ocean temperature difference energy conversion, and relates to an energy conversion device that collects ocean temperature difference heat energy through a phase change power heat pipe, converts the volume change of a phase change material into mechanical energy of a hydraulic system, and then converts it into electrical energy. Background technique [0002] Most of the marine detection equipment is powered by batteries to maintain the battery life and detection capabilities of the marine detection equipment. Ocean temperature difference energy conversion technology (OTEC) usually uses relatively warm tropical water to drive turbines to generate electricity, and then pumps lower temperature water from the depths of the ocean to condense water vapor into liquid for recycling. Or at the hydrothermal vent in the deep sea, the thermal energy of the hydrothermal fluid is used to convert it into electrical energy, and th...

AI Technical Summary

Problems solved by technology

[0003] This battery power supply method has certain defects, mainly in the following aspects: First, the battery storage energy is limited, which limits the endurance and detection capabilities of marine detection equipment

Second, the OTEC ocean temperature difference energy power generation cycle system is too large, and the weight and volume of the device are large, which is not convenient for ocean detection equipment to carry power generation equipment

Third, the thermal energy conversion method at the deep-sea hydrothermal vent requires the device to be fixed at the hydrothermal vent, which is not suitable for profile-moving marine detection equipment

Fourth, as an efficient energy storage hydraulic component, the accumulator has high safety requirements, so the thick wall results in a large mass, and the equipment occupies a large volume. The compact marine detection equipment needs to plan a large space to place the accumulator
